In the wake of Kevin Mannix’s allegations about his past, Mike Erickson is jumping on his one decided advantage: his—largely self-funded—warchest.

Erickson just donated another $275,000 to his campaign, which brings his total contributions to over $1 million. He has used his campaign kitty to permeate the airwaves with ads.

Mannix had only raised $171,730 at the end of April, and consequently has enjoyed a far lesser presence on the air.
